Species Abundance Data

Species abundance data used for population models. Each csv file contains the data for each on of our focal species. The csv files for each species are labele with the first three letters of each of the species' name and genes. The first column of the data contains the name of the locality where the data was colected. The second column contains the locality treatment where Dentro means that the locality was excluded from livestock and Fuera means that the locality did not have a livestock exclusion fence. The third column contains the quadrat from which the data comes from and the fourth column contains the subquadrat. The fifth column contains the year in wich the data was taken. Columns X an Y contain coordinates which were used to assess dispersal from and to neighbor subquadrats. t1 contains abundance at time t and t2 contain the species abundance at time t+1. columns y1 to y16 are a matrix that indicate the year that the data were collected. If, for instance, the data was collected in 2010, then the y10 column will contain ones while the restt of the columns will contains zeros. The depth column indicates the soild depht of the subquadrat where the data was taken. Next comes the columns of interacting species' abundances where the column names contain the first three lettters of each species' name and genus. Because not all species in our study interact with the focal species, the remaining species were added together and allowed to interact with the focal species as a single “multispecies” for which interaction parameters were estimated. This column is labeled multi. Some species' interaction with the focal species change with soil depth so we added a matrix to identify which species' interactins do so. This matrix is also labeled with the first three letters of the species' name and genus and occupies the last columns of the datasets.
